Dr. Peter Hersh, the study doctor, will perform the procedures. The investigational AcuFocus Corneal Inlay (ACI) is intended to improve near vision in patients with presbyopia, which is the loss of near vision, and reduce dependency on reading glasses. Qualified participants will receive the procedure at no charge........ ]]> http://medicineworld.org/stories/lead/11-2009/nanoparticles-for-diagnosis.html http://medicineworld.org/stories/lead/11-2009/nanoparticles-for-diagnosis.html Fri, 06 Nov 2009 14:56:40 GMT Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade........ ]]> http://medicineworld.org/stories/lead/11-2009/how-the-heart-is-formed.html http://medicineworld.org/stories/lead/11-2009/how-the-heart-is-formed.html Fri, 06 Nov 2009 14:56:40 GMT While studying how the heart is formed, researchers at the University of Pennsylvania School of Medicine serendipitously found a novel cellular source of atrial fibrillation (AF), the most common type of abnormal heart beat. Jonathan Epstein, MD, William Wikoff Smith Professor, and Chair, Department of Cell and Developmental Biology, and Vickas Patel, MD, PhD, Assistant Professor of Medicine, have identified a population of cells in the atria of the heart and pulmonary veins of humans and mice that appear to be the seat of AF. The finding may lead to a more precise way to treat AF, with reduced side effects. Their findings appear online in the Journal of Clinical Investigation........ ]]> http://medicineworld.org/stories/lead/10-2009/blocking-heat-shock-protein-to-fight-cancer.html http://medicineworld.org/stories/lead/10-2009/blocking-heat-shock-protein-to-fight-cancer.html Fri, 06 Nov 2009 14:56:40 GMT Like yoga for office drones, cells do have coping strategies for stress. Heat, lack of nutrients, oxygen radicals all can wreak havoc on the delicate internal components of a cell, potentially damaging it beyond repair. Proteins called HSPs (heat shock proteins) allow cells to survive stress-induced damage. Researchers have long studied how HSPs work in order to harness their therapeutic potential........ ]]> http://medicineworld.org/stories/lead/10-2009/treating-steroid-induced-osteoporosis.html http://medicineworld.org/stories/lead/10-2009/treating-steroid-induced-osteoporosis.html Fri, 06 Nov 2009 14:56:40 GMT A recent study determined glucocorticoid-induced osteoporosis (OP) is now treatable with Teriparatide, a synthetic form of the human parathyroid hormone. Scientists found patients with glucocorticoid-induced OP who were treated with teriparatide for 36 months had a greater increase in bone mineral density (BMD) and fewer new vertebral fractures than those treated with alendronate. The findings of this study are reported in the recent issue of Arthritis and Rheumatism, a journal of the American College of Rheumatology (ACR)........ ]]> http://medicineworld.org/stories/lead/10-2009/for-regeneration-of-nerve-fibers.html http://medicineworld.org/stories/lead/10-2009/for-regeneration-of-nerve-fibers.html Fri, 06 Nov 2009 14:56:40 GMT Scientists at Children's Hospital Boston report that an enzyme known as Mst3b, previously identified in their lab, is essential for regenerating damaged axons (nerve fibers) in a live animal model, in both the peripheral and central nervous systems. Their findings, published online by Nature Neuroscience on October 25, suggest Mst3b or agents that stimulate it as a possible means of treating stroke, spinal cord damage and traumatic brain injury. Normally, neurons in the central nervous system (the brain and spinal cord) cannot regenerate injured nerve fibers, limiting people's ability to recover from brain or spinal cord injuries........ ]]> http://medicineworld.org/stories/lead/10-2009/gleevec-may-be-helpful-in-sclerodema.html http://medicineworld.org/stories/lead/10-2009/gleevec-may-be-helpful-in-sclerodema.html Fri, 06 Nov 2009 14:56:40 GMT Investigators have identified a drug that is currently approved to treat certain types of cancer, Gleevec, that could provide the first therapy for scleroderma, a chronic connective tissue disease for which a therapy has remained elusive. The news will be presented at the annual meeting of the American College of Rheumatology on October 18 in Philadelphia........ ]]> http://medicineworld.org/stories/lead/10-2009/making-better-stem-cells-from-adult-tissue.html http://medicineworld.org/stories/lead/10-2009/making-better-stem-cells-from-adult-tissue.html Fri, 06 Nov 2009 14:56:40 GMT A team led by researchers from The Scripps Research Institute has developed a method that dramatically improves the efficiency of creating stem cells from human adult tissue, without the use of embryonic cells. The research makes great strides in addressing a major practical challenge in the development of stem-cell-based medicine........ ]]> http://medicineworld.org/stories/lead/10-2009/effective-treatment-against-cancer.html http://medicineworld.org/stories/lead/10-2009/effective-treatment-against-cancer.html Fri, 06 Nov 2009 14:56:40 GMT Drugs made using unusual metals could form an effective therapy against colon and ovary cancer, including malignant cells that have developed immunity to other drugs, as per research at the University of Warwick and the University of Leeds. The study, reported in the Journal of Medicinal Chemistry, showed that a range of compounds containing the two transition metals Ruthenium and Osmium, which are found in the same part of the periodic table as precious metals like platinum and gold, cause significant cell death in ovarian and colon cancer cells........ ]]> http://medicineworld.org/stories/lead/10-2009/alzheimers-disease-declines.html http://medicineworld.org/stories/lead/10-2009/alzheimers-disease-declines.html Fri, 06 Nov 2009 14:56:40 GMT Cognitive abilities other than memory, including visuospatial skills needed to perceive relationships between objects, may decline years previous to a clinical diagnosis in patients with Alzheimer's disease, as per a report in the recent issue of Archives of Neurology, one of the JAMA/Archives journals........ ]]> http://medicineworld.org/stories/lead/10-2009/parkinsonism-and-urate-level.html http://medicineworld.org/stories/lead/10-2009/parkinsonism-and-urate-level.html Fri, 06 Nov 2009 14:56:40 GMT Parkinson disease progresses more slowly in patients who have higher levels of urate, a chemical that at very high level is linked to gout, researchers have found. While it's unknown whether the high levels actually somehow protect patients or simply serve as a marker of protection, the finding supports the idea that patients and doctors may one day be able to better predict the course of the illness........ ]]> http://medicineworld.org/stories/lead/10-2009/clues-to-human-disease-from-blood-counts.html http://medicineworld.org/stories/lead/10-2009/clues-to-human-disease-from-blood-counts.html Fri, 06 Nov 2009 14:56:40 GMT A new genome-wide association study published recently in Nature Genetics begins to uncover the basis of genetic variations in eight blood measurements and the impact those variants can have on common human diseases. Blood measurements, including the number and volume of cells in the blood, are routinely used to diagnose a wide range of disorders, including anaemia, infection and blood cell cancers........ ]]> http://medicineworld.org/stories/lead/10-2009/amyotrophic-lateral-sclerosis.html http://medicineworld.org/stories/lead/10-2009/amyotrophic-lateral-sclerosis.html Fri, 06 Nov 2009 14:56:40 GMT Premature aging of the immune system appears to play a role in the development of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, as per research researchers from the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center, the Weizmann Institute of Science in Israel, and Sheba Medical Center in Israel........ ]]> http://medicineworld.org/stories/lead/10-2009/african-american-lung-cancer-patients.html http://medicineworld.org/stories/lead/10-2009/african-american-lung-cancer-patients.html Fri, 06 Nov 2009 14:56:40 GMT Clinical research out of University Hospitals Case Medical Center has observed that African Americans with a common form of lung cancer have a lower frequency of drug-sensitizing genetic mutations, which may impact response to new cancer-fighting drugs. Published online in the Journal of Clinical Oncology, the study by Rom Leidner, MD, and his colleagues report that ethnicity plays a significant role in non-small cell lung cancer (NSCLC) genetics and more personalized therapys appears to be beneficial to cancer patients........ ]]>
